64MB transferTo chunk size is too large for win32
-------------------------------------------------

                 Key: CASSANDRA-793
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-793
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 0.5
         Attachments: 793.txt

As reported by ruslan usifov on cassandra-user, he sees exceptions like

java.io.IOException: Невозможно выполнить операцию на сокете,
т.к. буфер слишком мал или очередь переполнена
    at sun.nio.ch.SocketDispatcher.write0(Native Method)
    at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:33)
    at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:104)
    at sun.nio.ch.IOUtil.write(IOUtil.java:60)
    at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:334)
    at sun.nio.ch.FileChannelImpl.transferToTrustedChannel(FileChannelImpl.java:449)
    at sun.nio.ch.FileChannelImpl.transferTo(FileChannelImpl.java:520)
    at org.apache.cassandra.net.FileStreamTask.stream(FileStreamTask.java:95)

this appears to translate to "insufficient buffer space."

He also reports that reducing CHUNK_SIZE to 32MB fixes the problem.
